Interspecific introgression is considered a potential threat to endangered taxa. One example where this has had a major impact on conservation policy is the lesser white-fronted goose (LWfG). After a dramatic decline in Sweden, captive breeding birds were released between 1981-1999 with the aim to reinforce the population. However, the detection of greater white-fronted goose (GWfG) mitochondrial DNA in the LWfG breeding stock led to the release program being dismantled, even though the presence of GWfG introgression in the actual wild Swedish LWfG population was never documented...

SIGNIFICANCE: Dry eye disease (DED) imposes a substantial burden on patients, which can lead to significant economic consequences for society. We provide insights into the DED patient population and DED diagnostic/management practices in Canada, which to date have been inadequately addressed in the literature. PURPOSE: The purpose of this study was to describe DED patient demographic/clinical characteristics alongside DED diagnosis/management in university-based optometry clinics in Canada...

Sjögren's syndrome (SS) is a chronic autoimmune disease with complex and diverse clinical manifestations. It is characterized by lymphocyte infiltration of exocrine glands such as the salivary gland and lacrimal gland leading to insufficient secretion of the gland, manifested as dry mouth and dry eyes. In addition, it can involve extraglandular organs and cause systemic damage. The pathogenesis of SS is still unclear. At present, symptomatic treatment is the mainstay and there is a lack of effective therapy...

Huntington's disease (HD) is a progressive, multifaceted neurodegenerative disease associated with weight loss and gut problems. Under healthy conditions, tight junction (TJ) proteins maintain the intestinal barrier integrity preventing bacterial translocation from the intestinal lumen to the systemic circulation. Reduction of TJs expression in Parkinson's disease patients has been linked with increased intestinal permeability-leaky gut syndrome. The intestine contains microbiota, most dominant phyla being Bacteroidetes and Firmicutes; in pathogenic or disease conditions the balance between these bacteria might be disrupted...

Sjögren's syndrome (SS) is an autoimmune disorder characterized by mononuclear cell infiltration in the exocrine glands, which leads to sicca syndrome (xerostomia and xerophthalmia). The etiology of SS is unknown, but multiple environmental factors (infectious, hormonal and stress-related), as well as genetic factors, may play a role in its pathogenesis. The diagnosis of SS is complex considering its clinical and paraclinical parameters may not be very specific. The minor salivary gland biopsy (MSGB) has undoubtedly become crucial for classifying and determining the prognosis of SS...

BACKGROUND: Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by deteriorated exocrine gland function with associated lymphocytic infiltration. However, there are few pathological studies on bronchial glands in SS. In this study, we aimed to clarify pathological features of bronchial glands in SS. METHODS: We retrospectively evaluated infiltration of lymphocytes in the bronchial glands incidentally collected by transbronchial lung cryobiopsy (TBLC), which were performed for the diagnosis of diffuse lung diseases...

Autoimmune disorders are the third most common diseases in the United States, and affect the daily lives of millions of people. In this study, we analyzed patient samples, utilized a transgenic mouse model and human B cells to reveal Natural Killer Cell Transcript 4 (NK4) as a novel regulator that promotes the development of autoimmune disorders. NK4 was significantly elevated in samples from patients with Sjӧgren's Syndrome (SS). SS patients show elevated NK4 levels. There is a strong and positive correlation between the increased levels of NK4 and the duration of SS...

Although acute poststreptococcal glomerulonephritis (APSGN) and acute rheumatic fever (ARF) are well-known complications of group A streptococcus infection, concomitant occurrence of both diseases is rare. We report an 11-year-old Japanese girl with primary Sjögren's syndrome complicated by acute renal failure about 2 weeks after the onset of pharyngitis. Although histopathological findings of the kidney were not confirmative, APSGN was suggested by the spontaneous recovery of her renal function, typical latent period with high levels of antistreptolysin O and low serum levels of C3 but not of C4...

A 52-year-old woman was diagnosed as having anti-centromere antibody (ACA)-positive primary Sjögren syndrome (pSS). Eight years later, she visited our hospital because she had developed dyspnoea. She was diagnosed as having pulmonary arterial hypertension (PAH) with pulmonary veno-occlusive disease on the basis of the results of right heart catheterisation, a severe decrease in diffusing capacity of the lung for carbon monoxide (DLCO , 17%) and desaturation (69%) after a 6-minute walk test. She was also diagnosed as having limited cutaneous systemic sclerosis (lcSSc) because she had developed finger sclerosis...

BACKGROUND: Hyperactivation of B cells by activators has been demonstrated to play a central role in the pathogenesis of Sjögren's syndrome (SS). In this study, we found that artesunate (ART) can attenuate BAFF-induced B cell hyperactivation and SS-like symptoms in NOD/Ltj mice. PURPOSE: To determine the efficacy of ART in attenuating SS-like symptoms in vivo and explore the underlying mechanism in vitro. STUDY DESIGN: ART was intragastrically injected into SS-like NOD/Ltj mice...

BACKGROUND: To assess the reliability of the consensually agreed US definitions of major salivary gland lesions and the US scoring system for salivary gland assessment in patients with SS. METHODS: Nine experienced sonographers scanned and read the US images of both parotid glands (PGs) and submandibular glands (SMGs) in eight patients with primary and secondary SS in two rounds. A consensually agreed four-grade semi-quantitative scoring was applied in B-mode for morphological lesions: grade 0, normal; grade 1, mild inhomogeneity without anechoic or hypoechoic areas; grade 2, moderate inhomogeneity with focal anechoic or hypoechoic areas; grade 3, severe inhomogeneity with diffuse an- or hypoechoic areas occupying the entire gland or fibrous gland...

Background: This study is part of the EU-funded project HarmonicSS, aimed at improving the treatment and diagnosis of primary Sjögren's syndrome (pSS). pSS is an underdiagnosed, long-term autoimmune disease that affects particularly salivary and lachrymal glands. Objectives: We assessed the usability of routinely recorded primary care and hospital claims data for the identification and validation of patients with complex diseases such as pSS. Methods: pSS patients were identified in primary care by translating the formal inclusion and exclusion criteria for pSS into a patient selection algorithm using data from Nivel Primary Care Database (PCD), covering 10% of the Dutch population between 2006 and 2017...

Sjögren's syndrome is an autoimmune lymphocytic infiltrative disease that leads to chronic inflammatory and degradatory changes to exocrine glands and extra-glandular systemic organs. It rarely affects children and adolescents. In cases where adolescents are affected, a paucity of sicca symptoms, xerostomia, and xerophthalmia often leads to a missed diagnosis. Consequently, the first presenting sign of Sjögren's syndrome in adolescents may be heterogeneous, with varying clinical symptoms related to parotitis or systemic organ involvement...

OBJECTIVE: To analyze the correlations of saliva production and pH value with disease activity, disease severity, and oral health-related quality of life in patients with diffuse cutaneous systemic sclerosis (dcSSc) without concomitant Sjögren's syndrome (SS) or SS-related antibodies. METHODS: This cross-sectional study included 28 patients with dcSSc and matching healthy controls. Sialometric assessment and caries status were compared between the two groups. Clinical and laboratory parameters were used to evaluate disease severity, in accordance with the Medsger Severity Scale...

Recent evidence links rosacea to systemic disease, but there are not enough methodologic studies addressing this association in Asians. Our aim was to identify rosacea comorbidities in Koreans and establish a reference database. A multi-center, case-control study was performed where a total of 12,936 rosacea patients and 12,936 age- and sex-matched control subjects were identified from 2007 to 2018. Logistic regression was performed to find significant association between rosacea and Sjögren syndrome (odds ratio [OR] 2...

BACKGROUND: Significant overlap may occur between idiopathic interstitial pneumonia (IIP) and connective tissue diseases (CTDs) that do not meet the established classification criteria for any known CTDs (i.e., occult CTD). Performing minor salivary gland biopsy (MSGB) to detect occult primary Sjogren's syndrome (pSS) in IIP patients is not well studied. METHODS: Consecutive IIP patients underwent MSGB to determine the prevalence of positive MSGB findings. Furthermore, we characterised the clinical, physiological and serological profiles of the MSGB-positive patients...

Tuberculosis is a common disease but it keeps on surprising with its unique presentations. It has been reported as lung mass but here we are reporting a case of Tuberculosis presented as vasculitic lung mass. A 61 years old female, known case of hypertension and secondary Sjogren syndrome, on treatment, presented with history of mild dyspnea and generalised weakness with incidental finding of Right hilar mass on chest X-ray undergoes a CECT thorax and CT guided biopsy. Histopathology contrary to expectations revealed granulomatous vasculitis with no microbiological evidence of TB, responded to antitubercular treatment and there was almost complete regression of the lesion after 6 weeks of ATT...

BACKGROUND: Pulmonary disease is a potentially serious yet underdiagnosed complication of Sjögren's syndrome, the second most common autoimmune rheumatic disease. Approximately 16% of patients with Sjögren's demonstrate pulmonary involvement with higher mortality and lower quality of life. RESEARCH QUESTION: Clinical practice guidelines for pulmonary manifestations of Sjögren's were developed by the Sjögren's Foundation after identifying a critical need for early diagnosis and improved quality and consistency of care...
